DOOR-OPERATING MECHANISM.

Specification of Letters Eatent. fPatygntqgd Aug. 3%}, 1921.

Application filed December 26, 1819. Serial No. 347,372;

' general service cars.

The objects of'the invention are to provide a simple and efiicient door operating mechanism which ispositive in its action so arrangedthat no strain is placed upon the mechan sm tending to distort it, thus m1n1- mizing repairs; to provide a device which can be easily operated by the class of lever usuall employed forsuch purpose; and to provi e an operating device so arranged as to increase-the efiiciency of the car in unload- %Ihese and other objects are'accomplished by means of the arrangement disclosed on the accompanying sheets of drawings, in which- Figure 1 is a fragmentary side elevation of a general servicelcar embodying my inven- .tion;

Fig. 2 is'a transverse sectional view of the same taken Ei 1; a V

ig. 3 is a detail sectional view on an enlarged scale showing the door operating mechanism in one of its positions and .Figs. 4 ando are detail sectional views, parts being shown in elevation,and taken in the planes of lines 4-4 .and 5-5 of Fig. 2.

The various novel features of the invention willbe a parent from thev following description and the drawings, and will be particularly pointed out in the appended claims. i i vThis'invention is an improvement on the inthe plane of line 2-2 of arrangement disclosed in the Hart Patent No. 1,318,444, grantedOctober 14, 1919, and in ,view of the fact that many advantages are common to the door operating mechanism disclosed therein and in my present arrangement, only the particular improvements claimed herein'will be particularly described. p

I have chosento illustrate my invention in connection with a general service car hav ving s'idesf 1O', ends 11, and a floor composed largely of dump doors 12 which are pivotconnected. th ir inner ends to tie centcr sill structure 13, the framework of the car including transverse supporting and strengthening members 1 which are provided with stop members 15, upon which the dump doors 12 rest'in an open position.

This invention has to do primarily with a door operating mechanism. Having in mind the disadvantages of door operating devices heretofore employed and the advantages of the present door operating mechanism, attention is called to the fact that each of the dump doors is raised from an open position to a closed position separately and independently of any'other one of the doors. Shdably secured to the bottoni'of each one ofthe doors, at the outer edge and prefer ablymidwaythe-length of the same, is'a latch ldhaving a downwardly projecting finger 17, thefunction ofwhich will be re ferred to later.

As shown in full lines at the right-hand .side of Fig. 2, thedump door 12 is inits lower or open position. Under such conditions an operating shaft 18, which is later ally and bodily movable in a pluralityof slots 19 in the transverse frame members 14,

occupies its outermost position. With the shaft 18 in 1ts outermost position, each of the dump doors 12 may be raised 1nd v1dually and directly by hand by inserting any suitablestake 20 into a recelvlng socket 21 carried on the under side of each of the doors.

With the latch in its inward, non -functioning'position, the doors 12 may be raised into closed position, whereupon the latch will be'moved outwardly into a position where itr ests upon and is supported by the shaft 18 with the latter in its outermost position. Accordingly, the door 12is supportedin its raised or closed position by the operating shaft through the sliding latch 16. This supporting arrangement, however, is a temporary one, but as soon as all of the dump doorshave been raised into closed position and their slidably mounted latches have been moved outwardly by hand to rest upon the associated shaft, as indicated in Fig. 3, the shaft may be moved laterally inwardly to a position under the doors for permanently supporting the latter. During the inward movement of the shaft 18, it engages the dependent fingers 17 on the latches 16, cansing the latches to be moved inwardly at least to a point where the outer edges of the latches are flush with the outer edges of the dump doors 12,as shown at the left-hand side of F i 2. It is apparent that after the shaft is now moved outwardly beyond the outer edges of the dump doors, the latter are free to drop into an open position for dumping purposes. It is seen, therefore, that the dump doors are raised directly and independently by hand and are temporarily held in closed position by the shaft through the overlying latches, the load later being transferred permanently to the shafts when the shafts are moved inwardly under the doors, at which time the latches also are moved inwardly into a non-latching position, the shafts in their innermost positions under the doors forming a permanent supporting arrangement. lVhen the shaft in any section of the car is moved outwardly, all of the doors in that particular section of the car supported by the associated shaft are dropped simultaneously.

The slots 19 as here shown extend slightly inwardly and upwardly from the sides of the car, so that the doors 12 are given their final closing movements'as the shafts are moved inwardly. In this particular case I have provided means to make the operation of the shafts positive in a manner to meet the various requirements under service conditions. This means includes arms 22 which are fixed on and turn with the shafts, it being understood that each shaft preferably has at least two such arms spaced thereon. Pivotally connected to the free end of each of said arms is one end of a link 23, while the other end of which in each case is connected preferably to any stationary part of the car, such as the frame member 14. From this arrangement it is apparent that when the shaft, as shown at the right-hand side of Fig. 2, is rotated in a counterclockwise direction, it will be moved toward the left throughthe slot 19 in a positive manner until it reaches its inward limit of movein'ent, as shown at the left-hand side of Fi 2. The arm 22 and its link 23 in each case in such position lie in a straight line forming a secondary lock, the primary lock, of course, being the usualratchet and pawl mechanism a at the end of each shaft. As said shafts a e moved inwardly under the doors they shift the latches 16 inwardly and give to the doors their final closing positions in which the doors 12 are supported. To permit the dump doors 12 toopen, the shaft, as shown at the left-hand side of Fig. 2, is rotated ina countercloclnvise direction, whereupon, through the linkage connection, it will be moved tdivard the left througli the slot 19 in'a positive maint ins shaft being ari ested iii its iitlier limit of movement at the outer'end of the slot, as shown, for on ample, at the right-hand side of Fig. 2. During an inward movement of the shaft, it will be understood that the free end of the link 23 is depressed a certain amount and then rises into the strai ht line position with respect to its associated arm to form the secondary lock for the shaft. This extreme or locked position of the shaft is broken by a rotation of the shaft in the proper direction, whereupon the free end of the link 23 in each case is lowered a certain predetermined amount and then is raised slightly as the shaft'reaches its outer limit of movement. 1 By using this door operating mechanism not only is the use of chains obviated, but also it is unnecessary to provide the shafts with gear members and also it is unnecessary to provide a stationary part of the car with racks to mesh with the shaft gears during the operation of the doors.

It is my intention to cover all modifica tions of the invention falling within the spirit and scope of the following claims.

I claim: r

1. In a. general service car having aplurality of doors, means for directly raising said doors individually, and'mean's including av door control shaft having a supporting and a nonsupporting position with respect to an associated door and a pivotally mounted link for locking one of said doors in raised position.

V
